What Is BPH (Benign Prostatic Hyperplasia)?
Benign Prostatic Hyperplasia, commonly known as BPH or enlarged prostate, is a non-cancerous enlargement of the prostate gland that occurs naturally as men age. The prostate gland sits just below the bladder and surrounds the urethra - the tube that carries urine from the bladder out of the body.
As the prostate enlarges, it squeezes the urethra like a clamp, making it harder for urine to flow freely. BPH is extremely common: it affects about 50% of men by age 60 and up to 90% of men by age 85. While BPH is not prostate cancer and does not increase cancer risk, it can significantly impact quality of life due to urinary symptoms.
The normal prostate weighs about 20-25 grams. In BPH, it can grow to 50, 80, or even over 100 grams, progressively worsening urinary function.
Symptoms of BPH (Lower Urinary Tract Symptoms)
BPH causes a group of urinary problems collectively called Lower Urinary Tract Symptoms (LUTS). These symptoms develop gradually and worsen over time:
- Frequent urination: Needing to urinate more often than usual, especially 8 or more times per day.
- Nocturia: Waking up multiple times at night to urinate, disrupting sleep.
- Urgency: A sudden, strong urge to urinate that is difficult to postpone.
- Weak urine stream: The flow of urine is slow, thin, or lacks force.
- Hesitancy: Difficulty starting urination - standing and waiting for the stream to begin.
- Intermittent stream: The urine flow stops and starts repeatedly.
- Incomplete emptying: Feeling that the bladder has not fully emptied after urination.
- Straining: Needing to push or strain to begin or maintain urination.
- Dribbling: Urine continues to dribble after finishing.
In severe cases, BPH can lead to urinary retention (complete inability to urinate), urinary tract infections, bladder stones, or kidney damage due to back-pressure.
The Traditional Approach: TURP Surgery
Transurethral Resection of the Prostate (TURP) has been the standard surgical treatment for BPH for decades. It is often called the "gold standard" surgery for enlarged prostate.
In TURP, a surgeon inserts a specialized instrument called a resectoscope through the urethra (via the penis) and uses an electrical loop to cut away the excess prostate tissue that is blocking urine flow. While TURP is effective at relieving symptoms, it carries notable risks:
- Spinal or general anesthesia: Required for the procedure.
- Retrograde ejaculation: Occurs in 65-75% of men after TURP. Semen flows backward into the bladder instead of out through the penis during ejaculation. While not harmful, it effectively causes infertility.
- Erectile dysfunction: Reported in 5-10% of patients after TURP.
- Urinary incontinence: Temporary or occasionally permanent loss of bladder control in 1-3% of cases.
- Bleeding: Significant bleeding requiring blood transfusion occurs in about 2-5% of cases.
- TUR syndrome: A rare but serious complication from absorption of irrigation fluid during surgery.
- Catheter requirement: A urinary catheter must be kept in place for 1-3 days after surgery.
- Hospital stay: Typically 2-3 days.
- Recovery: 4-6 weeks before returning to full activity.
The Cure Without Cut Approach: Prostate Artery Embolization (PAE)
Prostate Artery Embolization (PAE) is a modern, minimally invasive procedure performed by an Interventional Radiologist. It shrinks the prostate by blocking the blood vessels that feed it - all through a tiny needle puncture in the wrist or groin.
How it works: The prostate, like any organ, needs blood supply to maintain its size. In PAE, the interventional radiologist threads a thin catheter (tube) through an artery to reach the tiny arteries that supply blood to the prostate. Microscopic particles are then injected through the catheter to block these arteries. With its blood supply reduced, the prostate gradually shrinks over the following weeks and months, relieving the pressure on the urethra.
The procedure step by step:
- Access: Under local anesthesia, a tiny puncture is made in the wrist (radial artery) or groin (femoral artery). You remain awake and comfortable throughout with light sedation if needed.
- Navigation: A thin catheter is guided through the arterial system under real-time X-ray (fluoroscopy) guidance until it reaches the prostate arteries.
- Embolization: Tiny microspheres (particles smaller than a grain of sand) are injected to block the prostate arteries on both sides. This cuts off the blood supply to the enlarged tissue.
- Completion: The catheter is removed. A small bandage is placed on the puncture site. No stitches are needed.
The procedure typically takes 1-3 hours, depending on the complexity of the arterial anatomy.
TURP vs Prostate Artery Embolization: A Comparison
| Factor | TURP (Surgery) | Prostate Artery Embolization (Cure Without Cut) |
|---|---|---|
| Anesthesia | Spinal or general anesthesia | Local anesthesia with light sedation |
| Approach | Instrument inserted through the urethra | Tiny needle puncture in wrist or groin |
| Retrograde ejaculation risk | 65-75% | Less than 5% |
| Erectile dysfunction risk | 5-10% | Very rare (less than 1%) |
| Urinary incontinence risk | 1-3% | Extremely rare |
| Post-procedure catheter | 1-3 days required | Usually not required |
| Hospital stay | 2-3 days | Same-day or overnight |
| Recovery time | 4-6 weeks | 3-7 days |
| Symptom improvement | Rapid (within days) | Gradual over 1-3 months |
| Best suited for | Moderate prostate enlargement | All sizes, including very large prostates (>80g) |
Who Is a Good Candidate for PAE?
Prostate Artery Embolization may be right for you if:
- You have moderate to severe BPH symptoms that are not adequately controlled with medications (alpha-blockers like tamsulosin, or 5-alpha reductase inhibitors like finasteride).
- You want to avoid the sexual side effects of TURP, particularly retrograde ejaculation.
- You have a very large prostate (over 80-100 grams), where TURP becomes more challenging and risky.
- You are on blood-thinning medications that make traditional surgery risky.
- You have other medical conditions (heart disease, lung disease) that increase the risk of general anesthesia.
- You prefer a less invasive approach with faster recovery and no catheter.
- You are experiencing urinary retention and have a catheter in place that you wish to be free from.
PAE is not suitable for patients with suspected prostate cancer, active urinary infection, or certain types of arterial disease that prevent safe catheter navigation. A thorough consultation and imaging evaluation with Dr. Agarwal will determine if PAE is the right choice for your specific situation.
Recovery After Prostate Artery Embolization
Recovery from PAE is significantly easier than from TURP:
- Same-day or next-day discharge: Most patients go home the same day or the following morning.
- Mild discomfort: Some patients experience a mild burning sensation during urination, pelvic discomfort, or low-grade fever for a few days. These are normal and resolve quickly with simple medications.
- No catheter: Unlike TURP, most PAE patients do not need a urinary catheter after the procedure.
- Return to work: Most patients resume normal activities within 3-7 days.
- Gradual improvement: Urinary symptoms begin improving within 2-4 weeks and continue to improve over 1-3 months as the prostate shrinks. Studies show average prostate volume reduction of 25-40% and significant improvement in urinary symptom scores.
- Follow-up: Ultrasound and symptom assessment at 1 month, 3 months, and 6 months after the procedure.
Frequently Asked Questions
What is Prostate Artery Embolization (PAE)?
Prostate Artery Embolization (PAE) is a minimally invasive, non-surgical procedure performed by an Interventional Radiologist to treat an enlarged prostate (BPH). A thin catheter is inserted through a tiny puncture in the wrist or groin and guided to the arteries supplying the prostate. Microscopic particles are then injected to block these arteries, reducing blood flow and causing the prostate to gradually shrink. The entire procedure is done under local anaesthesia, and most patients go home the same day.
Is PAE better than TURP surgery?
PAE and TURP are both effective treatments for BPH, but they differ in important ways. PAE has a significantly lower risk of sexual side effects such as retrograde ejaculation (less than 5% vs. 65-75% with TURP) and erectile dysfunction. PAE also requires only local anaesthesia, involves no catheter in most cases, and allows recovery within 3-7 days compared to 4-6 weeks for TURP. However, TURP may provide faster symptom relief, while PAE improvement is gradual over 1-3 months.
How soon will urinary symptoms improve after PAE?
Unlike TURP, which provides near-immediate symptom relief, PAE works gradually as the prostate shrinks over time. Most patients begin to notice improvement in urinary flow and frequency within 2-4 weeks after the procedure. Significant improvement typically occurs over 1-3 months, with studies showing average prostate volume reduction of 25-40%. Maximum benefit is usually achieved by 6 months post-procedure.
Does PAE affect sexual function?
One of the major advantages of PAE over traditional TURP surgery is its minimal impact on sexual function. The risk of retrograde ejaculation after PAE is less than 5%, compared to 65-75% after TURP. Erectile dysfunction is very rare, occurring in less than 1% of PAE patients. Many men specifically choose PAE because it preserves normal sexual and ejaculatory function while still effectively treating their urinary symptoms.
Who is a good candidate for PAE?
PAE is suitable for men with moderate to severe BPH symptoms that are not adequately controlled with medications such as tamsulosin or finasteride. It is particularly beneficial for men who want to avoid sexual side effects of surgery, those with very large prostates (over 80-100 grams), patients on blood-thinning medications, or men with medical conditions that make general anaesthesia risky. A consultation with Dr. Rohit Agarwal, including imaging evaluation, will determine whether PAE is the right option for your specific situation.
